javascript - Testing animations angular 1.2+ -

anyone know how test animations in angular? animations built using either $animateprovider or angular.module('', []).animate() ? i'm building animations library, , it's nice, can't find proper way test animations using $animate. never work. have hacked work, i'm pretty recreating animations inside each test. make sure it's not animations, created new 1 on test. got straight out of angular's source code , still not work.

describe('testing async animations', function() {   var = false;   beforeeach(module('nganimate'));   beforeeach(module('nganimatemock'));   beforeeach(module(function($animateprovider){     $animateprovider.register('.fade', function(){       return {         enter: function(element, done){           console.log('here');           = true;           done();         }       };     });   }));    /* done() method mocha provides.      make work in jasmine, follow      example using asynchronous test */   it("should asynchronously test animation", function() {     inject(function($animate, $compile, $document, $rootscope, $rootelement) {       var element = $compile('<div class="fade">hello</div>')($rootscope);       $rootelement.append(element);       angular.element($document[0].body).append($rootelement);       $animate.enabled(true);       $animate.enter(element, $rootelement);       $rootscope.$digest();       expect(am).to.be(true);      });   });  }); 

i correct in way test animations, @ time angular made change ngmocks in v1.2.16 screwed up.
